[volt-nuts] Solartron 7081 serial comms

Looks like my memory is faulty and that I need a straight through cable (see my earlier post dated  Friday, December 02, 2011).

Addendum: Serial port will talk to a Solartron 7151 OK.

Well that's odd.  I just tried to talk to three different 7081s from two different computers via the serial port using Putty and a null-modem cable.

Port set for 9600,8,n,1   7081 dip switches in the OFF position.

Result a deafening silence even after an "OUTPUT,RS232,ON" command typed blind at the Putty console.

I have buzzed out the serial cable which looks like:

artial_handshaking>

I know this has worked before as I used the serial port for calibration last year.

Should I be using a straight-through cable?  My memory says no, but ...

I even rolled back Windows 10 Creators Update in case that was the culprit.

Help!
Dave
